UNITED STATES WILLIAM R. SATTERLY, OF SETAUKET, NEW YORK.

REEFING- FOB/E ANI) AFT SAILS.

T o all whom it may concern:

Be it known that I, VJLLIAM R. SATTERLY, of Setauket, in the county ofSuiolk and State of New York, have invented a new and useful Improvementin Fore and Aft Sails for Vessels; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1, is a side view of a mast, boom, gaffand sail with my invention applied. Fig. 2, is a. similar Viewexhibiting only the inner portion of the sail, the outer portion and thegaff being removed. Fig. 3, is a top view of the throat of the gaff.

Similar letters of reference indicate correspending part-s in theseveral ligures.

To enable others to make and use my invention I will proceed to describeits construction and operation.

A, is the mast; B is the boom; C, the galt;

lD, the throat halyard; and E, t-he peak hal yard, all applied andoperating in the usual manner except that the throat of the gai C, hasapplied to it for the purpose of confining it to the mast, a movable bowE, (Figs. l, and 3,) of iron or other metal, which is connected by adouble eye a, c, (Fig. 3) on one side, and by a hook and eye Z), 0, onthe other side to permit the gaff to be easily and quickly detached fromthe mast.

G, and H, are the two triangular portions of the sail the inner portionG, being secured to the boom and the outer portion being secured to thegaii" and the two lit-ting together, as shown in Fig. l, to form a sailof the form commonly used with a boom and gai), and being securedtogether at their junction by a series of loops d, el, known to marinersas keys 7 which can be all let go by unfastening the one known as theking key shown at 5, in Fig. l. The inner portion Gr, is furnished atits upper corner with a ring e, which is attached to the hook f, on thegait when the two portions of the sail are in use as shown in Fig. l,but which has the throat halyard D, attached when only the portion G, isin use as shown in Fig. 2. The outer portion H, is furnished at itslower corner with a ring 7, to receive the hook g, of the sheet or outhauler h.

When the two portions Gr, II, of the sail are combined as shown in Fig.l, they make a sail which may be considered in all essential respectsthe same as the sails ordinarily used and handled in the same manner andwhich might if furnished with points be reefed in the same manner,thoughI do not think more than one reef will be necessary as the furtherreduction can be more advantageously effected by taking away the p artII, which is eiiected as follows. The king key at 5, is first unfastenedand the gaff and the whole sail then lowered down to the boom. The ga isnext disconnected from the mast by unfastening the bow F, and alsodisconnected from the halyards and the portion I-I, of the saildisconnected from the outhauler. The throat halyard is then attached tothe ring e,` and the port-ion Gr, of the sail hauled up as shown in Fig.2, and the gaff and portion H, may be stowed away till again required.The portion G, of the sail constitutes a very effective and safe trysailand if provided with points may be reduced by reefing it to the boom inthe ordinary manner of reducing sails.

This construction of the sail is not intended to dispense with thegafftopsail,which may be applied in the usual manner and in fact it doesnot necessitate any change in the rig of a vessel, to which it isapplied, but a vessel of ordinary rig may have it applied at the mereexpense of the new sail or sails or the alteration of the old.

The triangular sail I do not claim as my invention; but

Having thus described my invention, what I claim and desire to secure byLetters Patent is- The combination with and above the triangular sail Gof another triangular sail ILI
